TYPEWRITING MACHINE Application led April 9,

To all whom t may concern.'

Be `it known that I, GEORGE GoULD Go- ING, a citizen of the United States, residing at Middletown, in the county of Middlesex and State of Connecticut, have mvented certain new and usefulmprovements in Typewriting Machines, of which the following is Iso a full, clear, and exact description, such as will enable other skilled in the art to which it appertains to make and use the same.'

This invention relates to typewriting machines and in some of its details particularly to improved shifting mechanism for varying the relative positions of the platen roller and type so as to bring different rows of characters on the type bars into position to engage the platen roller.

It is an object of the invention to provide improved shifting mechanism of the class mentioned which is simple and inexpensive in construction and positive, accurate and 'silent in operation.

It is a further objectto provide in a mechanism of the class mentioned, an improved means for positively ,locking the case shiftable member, in normal operative position and which is releasable by the shift operating mechanism.

It is a further object to provide a shifting mechanism ofthe class mentioned with improved mechanism for holding the case shiftable frame or member in normal-position Y and for limiting the shifting movement thereof in either direction.

Another object is to provide an improved anti-friction bearing mechanism for guiding the case shift frame of typewriting machines.

Other objects will be in part obvious in connection with the following detailed description of the invention, and in part pointed out therein.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the Scope of which will be indicated in the following claims.

Xn illustrative but preferred embodiment of the invention is shown in the accompanyin drawings wherein;

Fi 3 is a detailed fragmentary view showing the locking and stop mechanism, the parts being in position corresponding to the normal operating position of the carmage;

Fig. 4 is a view similar to Figure 3 showing the position of the parts-when the case shift frame'is moved upwardly;

Referring to the drawing for a detailed f platen carriage extending through the open y y side of the rail, bearing balls being disposed between the supporting'bar and inner surface of the rail. This bearing construction per se forms no part of the present invention but is claimed in a separate application filed by me of even date herewith, now Patent vNo'. 1,522,011, January v6, 1925. Detailed description of such construction is therefore considered unnecessary.

A shiftable type carriage, case shift frame or segment 5 is mounted adjacent to the platen carriage ,so that type bars (not shown) carried by the former may engage with the platen roller when moved rearwardly. This carriage 5 is mounted for vertical case shifting movement" relative to the platen so as to brlng the different characters on the type bars in alignment with the impact surface of the platen roller in a manner understood in the art. Y This mounting vertical movement'.

comprises vertically shiftable hollow bear# 'ing members or ball rails or guides 6 spaced apart and secured' to and supported by member 7 of the case shift frame. 'There' are preferably two of ,these guide members of Similar construction, but it is obvious that more or less may be used. Each ball rail is provided with an open side having three internal ball races for receiving balls 8,. The latter contact on three sides with Va vertical fixed bearing or guide rod 9 received within the associated member 6 and connected by a projecting plate or lug 10 of the frame structure 11. The plate 10 is seated and secured within a slot in the ro'd 9 providing a firm structure to guide the type carriage inits Each set of these balls are retained in position by mea-ns of a ball separator or cage 12 adaptedto support them in spaced relationship to provide bearings along the companion member 6 and rod 9 so as to support the carriage firmly in accurate alignment at all times. Each ball separator is provided with an extension 13 having a pin 14 engaging a slot disposed intermediate the ends of a lever 15 pivoted at one end to the frame 11 and having its'opposite end forked for engagement with a moving part ofthe case shifting mechanism. The purpose of this construction is to adjust the separatorsin accordance with the extent of rolling movement the balls receive when the case shift frame is shifted, causing the separators to travel in unison with the balls and avoiding undue friction. To aid in obtaining this result each ball separator is connected to the lever 15 intermediate the ends thereof whereby the throw of the cage is less than the movement of the shift frame.

For shiftingv the carriage or case shift frame .5 vertically in leither direction operating mechanism controlled by. finger keys 17 and 18 is keys 18 being employed in the present instance at opposite sides of the machine. Each key has a locking member 19 pivoted thereto for holding the keys depressed and urged byja spring 20 away from locking positlon.l ach'locking member has jan inclined notch 21 inthe shank thereof adapted to engage the correspondingly inclined edge of theA plate 22 when depressed and-simultaneously moved rearwardly. It will be 'understood that the lockingv mechanism will be held in locking position against the tension of s ring 20 by engagement of the inclined notc with the' edgeof'the plate 22, the pressure exerted by -springs 23A and 24 o n the keys tending to return the same to normal position after being depressed and thus hold-y ing the locking button orV key inlocking position until manual release is accompllshed .by depressing the key 17 or 18, or by depressling the locking key and moving it from locking position.

provided,two keys 17 and twoV carrying rollers 29 adapted to contact with the shift key 17 or 18.- Links 30 are connected at spaced portions o-f the shaft 25 -and to the carriage or vcase shift frame 5, each link beirg provided with an offset 31 having an adjustable pin, lug or stop 32.-

A locking plate 33 is pivotally mounted adjacent each shift link 3() to a bracket 34 'secured to the base plate l and pressed to normal locking Each of these locking plates is provided with a lug or projection 36 extendlngfrom one edge thereof, and disposed adjacent thereto is a cam member 37 rigidly mounted for'rotation with the shaft 25. Each locking osition by a spring .35.'

.plate 33 is also provided near its upper end with aA locking recess .38' having square lateral edges, and spaced from .this recess on the opposite sides thereof are upper and lower lugs or stops 39 and 40:U A

The lug 32 is adjustable in a vertical slot 32 in the offset' 31 to provide adjustment with respectrtolocking recess 38 and limit stops 39 and '40. To' aid inadjustment of each lug 32 a thin plate 32a is pivoted to the associated link 30 and has a slot 32b in an angularly disposed portion thereof. This slot is stra-ight or curvedv eccentrically to the pivot point of the'- corresponding plate 32a. Rocking of each plate on its .pivoted point when the associ-ated lug 32 is loosened will adjust the latter vertically in itsslot and support the same in position until tightene Y Each shift key. 17 is pivoted near itsrear of the machine and lying in positionY to -conlll() end at 41 extending to the forward portion l i tact with the roller 29 of associated arm 28a.'

Each key- 18 is pivoted intermediate. its ends at 42 having a rearwardly extended portion 18,a lying in position to Contact with the under side "of roller 19 an arm 28". 'Springs' 43 are each connectedat one end to parts of the frame and at theopposite end? to one of the forwardly extending arms 28,

the springs being tensioned to support the `2 said arms and functioning in the operation of the locking mechanism in a manner hereinafter described. The. lowerends of these springs may be' adjustably connected to L the arms 28v at different distances from the shaft 257 -a series of openings 44 being.pro vided in the arms 28L forthis purpose.

The operation of the carriage shifting mechanism 'is as follows: Supposing the A parts to be locked in normal operating po. 'sition as shown in Figs. 2 and vv3 and it is desired lto shift the type carriage orishift frame to position to bring another row of characters on the type bars, figures for exin its bearings in the supporting arms 26 'against the tenslon of the sprmgs 43. Tlns initial movement of shift shaft imparts corresponding movement 1n a counter-clockwlse direction to the lock-operating cams causing the latter to engage lugs 36 on the locking plates 33 and forcing the same against Athe tension of springs 35 into position to disengage the locking pins from slots 38. This releases the carriage to upward or downward A movement. Further depression of the key 18 results in bodily movement upwardly of the shaft 25 the same swinging with its supporting arms 26 about the pivotal points thereof. It will be notedin this connect-ion that the tension of springs43 is sufficient to support the arms 2,8EL in such a manner as to cause the upward movement of the carriage 5 as depression of the key continues. '[he shifting movement of the Acarriage 5 is stopped in `upward limiting positionby engagement of the pins or stops 32 with the upper limit stops 39 of the locking plates, the ,elements assuming positions shown in Fig. 4. It will thus be seen that shaft 25 is adapted to be given rotatory movement, prior to movement of the carriage 5, to unlock the latter and to be given subsequent bodily movement to shift the carriage into a new position.

If the carriage 5 is to be moved d-ownwardly, as when it is desired to write capitals. either one of the keys '17 is depressed against the tension of its spring 24, the key engaging roller 29 of the associated arm 28 and imparting to the shift shaft 25 an initial 4 rotatory movement in counterclockwise direction causing the cams 37 as before to move the lockingplates into carriage releasing position. Continued actuation of. the key 17 causes the shaft 25 to move down-' wardly with its pivotal supporting arms carrying with it carriage 5. Movement in this direction is limited by engagement of the pins 32 with the lower limit lugs 40 of the plates 33. During this final movement arms 28b fulcrum through roller 29 on extensions 18a of the keys 18 as will be obvio-ns.`

After movement in a downward direction and upon releasing the depressed shifting ing means,

key 17, the carriage is automatically returned to normal or middle position by action of springs 43, or bygravitywhen 'the carriage has been shifted to itsupward position and the depressed key 18 has been released. The locking of the carriage 5 in`l normal position occurs automatically when the locking pins32 align with the locking recesses 38 in plates 33, the latter being urged into locking position by springs 35. It will therefore'V be seen that the carriage is positively locked in its normal operating position after having been shifted in either direction, and it cannot be moved from this position without retracting the locking plates 33 which can only be accomplished through initial operatibm of one of the shift keys as above described.

As many changes 4could be made vin the above construction and many apparently Widely dierent embodiments of this linvention could be made without departing from the scopethereof, it is intended that all m'atter contained in the above description or shown in the accompanying drawings'shall be interpreted as illustrative and n'ot in a limiting sense. j

It is also to be understoodathaty the 1anguage used in the following claims is intended to cover allv of the generic and speciic features of the invention yherein described, and all statements of the scope of the invention which, as a matter of language, might beV said to fall therebetween. l
